F_BA_RemSecsTone

The function of return type UDINT shows the elapsed time of a TON function (switch-on delay) in seconds.
The switch-on delay to be considered must be applied to the tonTimer input.

• As long as the switch-on delay is not activated, i.e. the input IN is set to FALSE, the output nRemTime is fixed at the time value to which the switch-on delay is programmed (value rounded down to full seconds).
• As soon as the switch-on delay has switched through, i.e. output Q is TRUE, the output nRemTime is fixed at "0".
